KMBC's Micheal Mahoney reported that James had just started speaking when Black ran up on stage and started criticizing James.

"This man just got through talking about exactly what the (expletive) he ain't (expletive) doing!" Black shouted.

He was forcibly removed by the mayor's security detail and other officers at the scene.

Mahoney reported that Black was apparently able to run down one of the side aisles of the darkened Gem Theater and throw down the Kansas City municipal flag just behind the mayor before getting to the podium.

James defended his security team.

"I'm not going to question my security detail." James said after the event.

The mayor was not hurt and does not believe the protester intended to harm him.

"The only way to have stopped that was to have them right by my side. We don't live in that way," said James.

This is the second time in his three years in office that James has had a security incident.

Two summers ago, James was at an outdoor event encouraging young and underage Kansas Citians not to cluster on the Country Club Plaza late at night.

James' security agents pushed him into a group of bushes when they heard gun shots in the vicinity.

Mahoney reported that a man who identifies himself as Derron Black’s campaign manager said Black intends to run for mayor in 2015.

"We're talking about systematic oppression that is continuing in our community," Black said on KMBZ radio. "So I'm trying to figure out a way of addressing these things."

Black was expected to hold a news conference on Wednesday afternoon, but cancelled it after being released from police custody.

"I'm not evening thinking about running in two years, to be honest," James said. "But if he wants to do that, that's fine. We welcome any challenge anybody wants to bring."
